Hello there, and thank you for posting your question here on brainly.

Do the steps in this order.

Subtract 3.2 from both sides.

10.2x + 3.2 = 4.6 ---> 10.2x = 1.4

Divide both sides by 10.2

10.2x = 1.4 ---> x = 1.4/10.2

Simplify the division.

1.4 / 10.2 ≈ 0.13

Hope this helped!! ☺♥

The population of a town increases by 4 % every year . In the last year the population of the town was 110000.

Answer:

114,400 and 118,976.

Step-by-step explanation:

Let's represent this using a function. Let's let:

$P(y)$ represent the total population, and $y$ represent the total number of years since last year.

We know that the population grows by 4% every year or 0.04 every year. This is exponential growth. We can write this as:

$P(y)=110000(1.04)^y$

Note that the coefficient is 110000 because that is the year we are starting with. Also, note that it is 1.04 because we are essentially adding .04 to the original population.

Anyways, to find the present population, set y equal to 1 (because 1 year after last year is the present year)

$P(1)=110000(1.04)^1=114400$
